Note that worn chain can be an indication of worn hoist
components. For this reason, the hoistās chain guide, hook
block and liftwheel should be examined for wear and
replaced as necessary when replacing worn chain.
Also, these chains are specially heat treated and hardened
and should never be repaired.

Chain
Lubrication
A
small amount of lubricant will greatly increase the life of
load chain. Do not allow the chain to run dry. keep it clean
and lubricate at regular intervals with Lubriplate
Ā®
Bar and
Chain Oil 10-R (Fiske Bros, Refining Co.) or equal lubricant.
Normally, weekly lubrication and cleaning is satisfactory, but
under hot and dirty conditions, it may be necessary to clean
the chain at least once a day and lubricate it several times
between cleanings.
When lubricating the chain, apply sufficient lubricant to
obtain natural run-off and full coverage, especially in the
interlink area.
LUBRICATION
Refer to Exploded View and Parts List on pages 10 thru 14.

Use of commercial or other manufacturesā chain and parts
to repair ShopAir Hoists may cause load loss.
TO AVOID INJURY:
Use only factory supplied replacement load chain and
parts. Chain and parts may look alike, but factory original
chain and parts are made of specific materials or processed
to achieve specific properties. See Figure 7.
Used motor oils contain known carcinogenic materials.
TO AVOID HEALTH PROBLEMS:
Never use used motor oils as a chain lubricant. Only use
Lubriplate
Ā®
Bar and Chain Oil 10-R as a lubricant for the
load chain.
The lubricants used in and recommended for the ShopAir
Hoist may contain hazardous materials that mandate
specific handling and disposal procedures.
TO AVOID CONTACT AND CONTAMINATION:
Handle and dispose of lubricants only as directed in
applicable material safety data sheets and in accordance
with applicable local, state and federal regulations.
Gears
The Protectorā¢ (620-111) should operate for the normal life of
the hoist without service. The device has been lubricated and
calibrated by CM
Ā®
and should not be adjusted.

If
the gears are removed from the housing, wipe the excess
gr
ease off the outside surfaces of the Protectorā¢ with a soft
cloth and degrease the remaining gears and housings. Upon
reassembly, add 2 oz. of the above grease to gears and
housing. Also, coat the spline on the end of the first pinion
and shaft (620-131) with a Molydisulphide lubricant such as
Moly-Duolube 67 (Hercules Packing Co.).
Bearings
Needle bearings (620-109, 620-114, 620-115, 620-128 and
620-164) are packed at assembly with grease and should
not need to be relubricated. However, if the housings (620-
113 and 620-107), liftwheel (620-127) or sheave wheel (620-
162) have been degreased, these bearings should be
greased using āCentury Lubricants HB-11, #3ā grease.
Seals
When reassembling the unit, wipe the inside surface of the
seals with āCentury Lubricants HB-11, #3ā grease.
Service Air Line Lubricator
The air line filter and lubricator is the only source of lubrication
for control valves and air motor. Fill lubricator with a good
grade air hoist motor oil or low machine oil (viscosity of 180
SSU at 100
0
F.). Multi-viscosity, detergent type oil is not
recommended. Feed one drop of oil for every 50 to 75 cubic
feet of air going through the air motor.
Hook Block
If the hook blocks are disassembled for inspection purposes,
wipe the grease from the hook knob and the hook knob
cavities in the hook blocks. At reassembly, coat the underside
of the hook knob and the knob bearing surfaces of cavities in
the hook blocks with Molykote BR-2-S (Dow Corning Corp.)
grease or equivalent.
Chain Guide, Liftwheel and Sheave Wheel
When the hoist is disassembled for inspection and/or repair, the
chain guide, stripper, sheave wheel (on double chain unit) and
liftwheel must be lubricated with Lubriplate
Ā®
Bar and Chain Oil
10-R (Fiske Bros. Refining Co.) prior to reassembly. The
lubricant must be applied in sufficient quantity to obtain natural
runoff and full coverage of these parts.
LLooaadd CChhaaiinn
See above for lubrication of the load chain.
Exterior Finish
T
he exterior surface of the hoist has a durable, scratch
resistant baked powder coating. Normally, the exterior
surfaces can be cleaned by wiping with a cloth.
